Display frame for photographs and the like and typically credit card-sized

ABSTRACT

A credit card-size plastics display frame defines a front rectangular opening and coplanar side grooves peripherally around this opening for receiving a photograph and a protective window in front thereof, the window being usable as a template to cut an appropriately sized photograph from a standard size picture for insertion in the display frame. The photograph and the window are installed in the frame by front loading through the rectangular opening. The rear wall of the frame defines panels which can be selectively, and reversibly, folded back to form a foot member to allow the frame to stand on a horizontal surface. A diamond-shaped cutout is defined in the rear wall to allow the display frame to be hung on a wall with a nail and to facilitate the removal of the photograph and window from the frame. The display frame is characterized by its universal credit card dimensions, the snap fit front loading mounting of the photograph and window, the reversibly extendible support stands, by the diamond-shaped cutout, and the window which also acts as a template to down-size a standard picture to the required dimensions for the display frame.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0035] With reference to the drawings and, more particularly, to FIG. 1, there is illustrated a novel display frame F which is typically made of a plastic material and by way of an injection molding process. The display frame F comprises a substantially rectangular rear wall 10 which peripherally defines a slightly forwardly projecting frame-shaped rim 12 (see FIG. 2) integral with the rear wall 10 and defining at the front end thereof an inwardly projecting peripheral lip 14. As seen in FIG. 1, on each front side of the frame-shaped rim 12, the lip defines a slightly convex inner edge 16 with each convex inner edge 16 extending between a pair of successive inner rounded corners 18 defined by the rim 12. The purpose of these convex inner edges 16 will be described in detail hereinafter.

[0036] The rear wall 10 defines a central diamond-shaped cutout 20 and four slots 22 extending diagonally outwardly therefrom and defining enlarged free ends 24. The rear wall 10 also defines near the outer edges thereof four linear slots 26 which run parallel to respective sides of the rear wall 10. The linear slots 26 have a dual function wherein the linear slots 26 act as score lines for facilitating the folding or deployment of support legs of the display frame F which will be described in detail hereinafter, and further act as undercuts for use in the injection molding process.

[0037] The rear wall 10, the rim 12 and the lip 14 define an inwardly facing peripheral shallow channel 28, as best seen in FIG. 2, which is adapted to receive the peripheral edges of a photograph P, or the like, and a protective window 30 typically made of a substantially flexible transparent plastics material.

[0038] One of the objects of the present invention is to provide a display frame which can be easily carried in wallets and the like and, more particularly, within integral pockets or plastic sleeves defined in such object-carrying articles. Accordingly, the outer dimensions of the display frame F are preferably, but not limitatively, similar to those of a credit card, whereby the display frame F might have a length of 86 mm±5 mm and a width of 54 mm±5 mm. Furthermore, the display frame F is made very thin such as to fit in the aforementioned credit card-receiving pockets and sleeves provided in wallets and the like.

[0039] Therefore, the display frame F defines a front substantially rectangular opening inwardly of the lip 14 such that the coplanar side channels 28 which extend peripherally behind this opening and the lip 14 can receive the outside edges of the photograph P and of the window 30.

[0040] Importantly, the photograph P and the window 30 are substantially rectangular while defining rounded corners and are sized such that their rounded corners are positioned in the display frame F substantially opposite the inner corners 18 and even slightly inwardly thereof. The photograph P and the window 30 both define between their respective rounded corners rectilinear edges 32 with the photograph P and the window 30 being sized such that their rectilinear edges 32 run at least partly behind the convex lips 14, as seen in broken lines in FIG. 1. The flexibility of both the photograph P and the window 30 allows the same to be front-loaded into the display frame F with a snap-like fit, and this is facilitated by the rounded corners of the photograph P and of the window 30 extending substantially opposite the inner corners 18 of the lip 14, and even slightly inwardly thereof, such as to clear the corners whereas the rectilinear edges 32 of the photograph P and window 30 can be easily snapped into engagement behind the convex inner edges 16 of the lip 14 and thus into the channels 28, the portions of the lips 14 overlapping the photograph P and window retaining these components in position in the display frame F.

[0041] It is noted that once the photograph P has been front-loaded into position in the display frame F, the transparent cover sheet or window 30 is positioned in a same way over the photograph P, that is by front-loading. It might also be possible to install both the photograph P and the window 30 in a single step.

[0042] Preferably, the window 30 is used as a template in order to cut an appropriately sized section of a photograph for insertion in the display frame F. The transparency of the window 30 further allows the original photograph and, more particularly, its section being cutout therefrom to be visible thereby ensuring that the proper section of the original photograph will be removed therefrom for subsequent use as the above-described photograph P within the display frame F of the present invention.

[0043] Obviously, the present display frame F can be of larger dimensions than those of a credit card such as to accommodate standard sized pictures (e.g., 3½″×5, 4″×6″, 5″×7″, 8″×10, 8″×12″, etc.) or other sheet-like articles of different sizes worthy of display.

[0044] Now referring generally to FIG. 3, the rear wall 10 defines four substantially triangular panel sections 34 each extending basically between a pair of successive diagonal slots 22 and a respective linear slot 26. The panel sections 34 remain attached to the rear wall 10 in view of the fact that each linear slot 26 does not reach the enlarged ends 24 of the two successive diagonal slots 22 between which such linear slot 26 extends. The linear slot 26 is thus spaced apart at each of the ends thereof from a respective enlarged end 24 of the diagonal slot 22 by approximately 8 mm of rear wall material. These portions of the rear wall 10 which extend between the ends of the linear slots 26 and the enlarged ends 24 of the diagonal slots 22 are identified by reference numeral 36 and functionally constitute hinges between the triangular panel sections 34 and the remainder of the rear wall 10, as described hereinbelow. Indeed, a selected one of the panel sections 34 can be pulled away from the plane of the display frame F and thus folded back so as to act as a foot member or stand which allows the display frame F to be supported at an angle on a horizontal surface S, as seen in FIG. 4. The rear wall 10 and its triangular panel sections 34 are designed such that the panel sections can be reversibly and repeatedly pivoted about the hinges 36 between the extended stand position thereof illustrated in FIG. 4 and the retracted position thereof of FIGS. 1 to 3.

[0045] With regards to the pivotable triangular panel sections 34, it is noted that the type of plastic used therefor and also for the rear wall 10 must have a certain resistance and, more particularly, a required flexibility in order to allow for numerous bends and deployments thereof without breaking at the hinges 36. On the other hand, the plastic has to be rigid enough that after bending, the panel sections 34 will remain in the selected, i.e. expanded or retracted, position thereof. Possible plastics material which are presently but not limitatively contemplated are polypropylene (PP), styrene/acrylonitrile copolymer modified with butadiene rubber (ABS) or modified with acrylate elastomer (SAN), high impact polystyrene (SB), polyacetal (POM), polyamide (PA), i.e. nylon resins, etc. All of these materials can also be reinforced. Furthermore, the plastic which will be selected to fulfill the above-mentioned physical requirements can also be generally transparent in order to offer more coloring possibilities.

[0046] Regarding the hinges 36 and the related linear slots 26 and enlarged ends 24, it is noted that the linear slots 26 are provided in order to reduce the effort required for bending the triangular panel sections 34 and also in order to assist the injection molding process. Indeed, the linear slots (approximately 0.8 mm wide) extending between the hinges 36 permit the formation of the undercut (lip) located at the front of the display frame F and used to mount the photograph P and the window 30 to the frame F. Indeed, a rear movable mold part of the injection molding tool defines rectangular forward ribs which form the linear slots 26 while extending forwardly up to the rear surfaces of the lips 14 with a fixed front mold part defining the slightly curved configuration of the inner edges 16 of the lips 14. It is these undercuts or lips 14 which allow for the easy front-loading of the photograph P and window 30 through the front of the frame F by defining a curve (see inner edges 16 in FIG. 1) having a large radius which peaks at about 0.5 mm in height at the middle of the frame F and which reduces gradually to zero at the inner corners 18. This basically allows for the corners of the photograph P and of the window 30 to be front-loaded substantially without bending in the display frame F with their linear edges being snapped into engagement behind the undercuts or lips 14.

[0047] The diamond-shaped cutout 20 defined in the rear wall 10 defines rounded apexes 38 which can be used for hanging the display frame F on a nail installed in a wall. Furthermore, the cutout 20 also facilitates the removal of the window 30 and of the photograph P from the display frame F by simply pushing on the photograph P through the cutout 20.

[0048] Accordingly, the features of the display frame F which are of interest reside in the universal credit card dimensions thereof; the front-loading of the photograph P in the display frame F, including the method of installing the photograph P and the window 30 in the display frame F by front-loading and with a snap-fit; the reversibly extendible panel sections 34 which act as support stands for allowing the display frame F to be supported on a horizontal surface, either along its horizontal or vertical orientation; the diamond-shaped cutout 20 defined in the rear wall 10 for allowing the display frame F to be hung on a wall and to facilitate the removal from the display frame F of the photograph P and of the window 30; and the use of the window 30 as a template to allow the user to cut a larger picture to a size appropriate for the present display frame F, i.e. the size of the illustrated photograph P, while allowing the user to clearly view the contents of the portion of the standard size picture which is being cut for the purpose of installation in the display frame F.

[0049]FIG. 5 illustrates a second embodiment of the present invention having a different rear wall configuration. More specifically, according to this embodiment, the rectangular rear wall 10′ defines two linear peripheral grooves 40 extending along a major portion of the longer sides of the display frame F′. The rear wall 10′ further defines two peripheral openings 42 extending along a major portion of the shorter sides of the display frame F′. The linear peripheral grooves 40 along with the peripheral openings 42 form a central rear wall portion 44 which cooperates with the lips 14 for retaining the window 30 and a photograph (not shown) in place within the display frame F′. The central rear wall portion 44 is integrally connected along the longer sides thereof to the frame-shaped rim 12. Furthermore, an integral connecting member 46 extends diagonally from each corner of the central rear wall portion 44 to strengthen the attachment thereof to the frame-shaped rim 12.

[0050] The central rear wall portion 44 defines a central diamond-shaped cutout 48 through which one may push on the photograph (not shown) to remove the same from the display frame F′, as explained hereinbefore with respect to the first described embodiment. The central rear wall portion 44 also defines two elongated openings 50 symmetrically disposed with respect to a longitudinal median axis of the display frame F′. Cutouts 51 are defined in the central wall portion 44 so as to form a pair of pivotable integral support stands 52. The support stand 52 are symmetrically disposed with respect to a transversal median axis of the display frame F′.

[0051] According to the illustrated embodiment, the support stands 52 have a M-shaped configuration. Each support stand 52 includes two external legs 54 connected to each other through a central tab or flap 56. Each external leg 54 is connected to the central rear wall portion 44 via a first live hinge 58 and a frangible connection 60 extending through the cutout 51. Accordingly, to pivot a selected one of the support stand 52 about its first live hinges 58, the frangible connections 60 thereof must first be broken into two distinct portions 60 a and 60 b. This could be accomplished by simply pulling on the selected support stand 52 to pivot it away from the plane of the display frame F′. As will be explained hereinafter, the broken portions 60 a and 60 b will cooperate to retain the support stand 52 in a non-functional retracted position thereof. A second live hinge 62 is defined in each external legs 54 to allow articulation thereof. The second live hinges 62 divide the external legs 54 into a first portion 63 and a second portion 65.

[0052] As seen in FIG. 7, once the frangible connections 60 of a selected one of the support stands 52 have been ruptured, the selected support stand 52 is allowed to be pivoted away from the plane of the display frame F′ about the first live hinges 58 thereof. During the first phase of the pivotal movement in the direction of arrow 64, the selected support stand 52 will essentially only pivot about the first live hinge 58 thereof. However, continuous pulling action on the selected support stand 52 above the second live hinges 62 thereof will eventually cause the support stand 52 to also pivot about the second live hinges 62 and, thus, cause the external legs 54 to be folded. Accordingly, the first portion 63 of the external legs 54 will be pivoted away from the plane of the display frame F′. Since the central flap 56 is connected to respective first portions 63 of the legs 54 and is disposed on opposite side of the pivot axis extending through the second live hinges 62 of the selected support stand 52, the central flap 56 will be moved in the opposite direction, i.e. towards the plane of the display frame F′. At a certain point, as illustrated in FIG. 7, the distal edge 66 of the central flap 56 will engage the photograph (not shown) and cause the same to bent with the window 30. From this position to the position illustrated in FIG. 8, the central flap 56 acts as a locking member to overcome the resiliency of the external legs 54 at the second live hinges 62 thereof. In other words, past the position illustrated in FIG. 7, the biasing force of the second live hinges 62 will urge the central flap 52 against the photograph (not shown), thereby preventing the second leg portion 63 from being pivoted towards their original position.

[0053] Further pivot of the first leg portions 63 of the selected support stand 52 about respective second live hinges 62 in the direction indicated by arrow 66 in FIG. 8 will bring the central flap 56 in engagement between the photograph (not shown) and one apex 68 of a diamond-shaped rear wall portion extending between the two support stands 52 about the central diamond-shaped cutout 48. In this position, the first leg portions 63 of the selected support stand 52 will act as a support foot for supporting the display frame F′ on a horizontal surface F′. As seen in FIG. 8, the central flap 56 will push on the apex 68 thereby causing the same to flex away from the plane of the display frame F′. As the apex 68 is resilient, it will tend to recover the original position thereof, thereby further urging the support flap 56 against the photograph (not shown). Accordingly, the friction between the apex 68, the central flap 56 and the photograph (not shown) will help maintaining the selected support stand 52 in its functional stand position to support the display frame F′ along a short orientation thereof, as seen in FIGS. 8 and 9. It is noted that the biasing force of the first and second pairs of live hinges 58 and 62 will also prevent the selected support stand 52 from being pivoted back to its original retracted position while supporting the display frame F′ on a horizontal surface S.

[0054] The first and second pairs of live hinges 58 and 62 are designed such that the support stands 52 can be reversibly and repeatedly pivoted between the stand position illustrated in FIGS. 8 to 10 and the retracted position thereof of FIGS. 5 and 6. When a selected support stand 52 is pivoted back to its retracted position, the associated broken portions 60 a and 60 b will snap into engagement so as to retain the selected support stand 52 in the plane of the display frame. However, if it is subsequently desired to displace the selected support stand 52 to the stand position thereof, the friction between associated broken portions 60 a and 60 b can be readily overcome by simply pulling on the selected stand 52.

[0055] According to another embodiment of the present invention, the frangible connections 60 could be replaced by snap-like fit cooperating members.

[0056] As seen in FIG. 10, the two support stands 52, which are symmetrically disposed relative to the median transversal axis of the display frame F′, may be both deployed to support the display frame F′ along the long orientation thereof instead of the short orientation thereof, as illustrated in FIG. 9.

[0057] As seen in FIGS. 5, 9 and 10, laterally spaced-apart ribs 70 extend from the undersurface of the lip 14 inwardly of the frame-shaped rim 12 to assist in positioning the photograph within the display frame F′.

A display frame for displaying a sheet-like article, comprising attachment means for retaining the article on said display frame, viewing means for allowing at least part of the article to be viewed when mounted to said display frame, and template means adapted to define limits of the article when cut from a second larger article such that the article is of dimensions appropriate for installation in said display frame.
 17. A display frame as defined in claim 16 , wherein said template means comprise a substantially transparent sheet means for allowing the article to be viewed when the second larger article has been cut down to size and which is adapted to double as a protective window secured to said display frame by said attachment means and in front of the article.
 18. A display frame for displaying a sheet-like article, comprising attachment means for retaining the article on said display frame, viewing means for allowing at least part of the article to be viewed when mounted to said display frame, and at least one support stand pivotally connected to a rear wall of said display frame along a first pivot axis, said support stand being reversibly pivotable between an inoperative retracted position wherein said support stand is substantially parallel to said rear wall and an operative extended stand position wherein said support stand extends at an angle with respect to said rear wall for allowing said display frame to be supported on a substantially horizontal support surface, said support stand having lock means adapted upon pivot of said support stand from said inoperative retracted position to said operative extended stand position thereof to displace relative to said first pivot axis, wherein in said operative extended stand position, said lock means engage one of said rear wall and said sheet-like article to retain said support stand in said operative extended stand position.
 19. A display frame as defined in claim 18 , wherein said lock means is pivotally displaceable about a second pivot axis which is, in turn, pivotally displaceable with respect to said first pivot axis.
 20. A display frame as defined in claim 19 , wherein said support stand includes a proximal end portion which pivots about said first pivot axis, and a distal end portion which pivots about both said first and second pivot axes, said lock means being connected to said distal end portion and extends on the opposite side of said second pivot axis, whereby during a first phase of a displacement of said support stand from said inoperative retracted position to said operative extended stand position, said lock means is pivoted about said first pivot axis, in a second phase, about said second pivot axis and then at a certain time in said second phase, a resiliency of said support stand urges said lock means against one of said rear wall and said sheet-like article.
 21. A display frame as defined in claim 18 , wherein said support stand is formed by cutout means defined in said rear wall, whereby said support stand is disposed in the plane of said rear wall when displaced to said inoperative retracted position thereof, and whereby said lock means contact said sheet-like article when said support stand is pivoted to said operative extended stand position thereof.
 22. A display frame as defined in claim 18 , wherein at least a pair of said support stands are symmetrically disposed with respect to a median axis of said display frame for allowing a selected one of said support stand to support said display frame onto the substantially horizontal support surface in a first orientation of said display frame, and for allowing both said support stands to be displaced to said operative extended stand position thereof such that said display frame may be disposed on the substantially horizontal support surface in a second orientation rotated by 90 degrees with respect to said first orientation.
